"Papers relating to the Blockade."] [Footnote 570: Hansard, 3rd.Ser., CLXV, pp.

1158-1230, and pp.
1233-43.] [Footnote 571: Mason's authenticated statistics, unfortunately for his cause, only came down to Oct.

31, 1861, a fact which might imply that after that date the blockade was rapidly becoming effective and which certainly did indicate that it was at least sufficiently effective to prevent regular and frequent communications between the government at Richmond and its agents abroad.

Did Russell have this in mind when he promptly incorporated Mason's figures in the papers presented to Parliament?
These figures showed that according to reports from four Southern ports, sixty vessels had entered and cleared between April 29 and October 31, 1861; unauthenticated statistics extending to the date December 31, presented by Mason of vessels arrived at and departing from Cuban ports showed forty-eight vessels, each way engaged in blockade running.

Seven of these were listed as "captured." Those reaching Cuba were described as twenty-six British, 14 Confederate, 3 Spanish, 3 American and 2 Mexican, but in none of these statistics were the names of the vessels given, for obvious reasons, in the printed paper though apparently included in the list submitted by Mason.
